Tospoviruses: Diagnosis, Molecular Biology, Phylogeny, and Vector Relationships

open access: closedAnnual Review of Phytopathology, 1992
The disease known as "spotted wilt" was first described in Australia in 1 9 1 5 ( 16) and shown to have a viral etiology b y Samuel et al i n 1930 ( 14 1 ). Since that time, viruses similar or identical to the tomato spotted wilt virus (TSWV) have been the cause of plant diseases epidemics in tropical, subtropical, and temperate regions throughout the ...

Insect Vectors of Phytoplasma Diseases in the Tropics: Molecular Biology and Sustainable Management

open access: closed, 2020
Phytoplasmas are pleomorphic, non-culturable, wall-less prokaryotes that colonize phloem tissues of several plant species inflicting yellows-type diseases. They are transmitted between plants by vegetative propagation, and insect vectors are the chief means of dissemination of phytoplasmas.

High performance capillary gel electrophoresis as a method to separate plasmid-DNA cloning vectors with very high resolution (below 100 bp) and its application in molecular biology

open access: closedJournal of Microcolumn Separations, 2000
A novel high resolution method for the separation of, both, linear and supercoiled circular plasmid DNA in the range of 3000–5600 bp is described. Employing ultradilute solutions of hydroxyethylcellulose (0.070–0.100% w/w) containing no intercalating agent, we were able to resolve plasmids as well as linear fragments with a size difference of about 100

Molecular Biology of Plant Virus-Vector Interactions

open access: closed, 1994
The movement of a virus from one plant host to another presents several special problems. Most plants are sessile and, thus, unless hosts are growing close enough to each other to have direct contact, virus transmission requires some agent. Most of the plant surfaces are covered with a cuticle and the cells are enclosed in walls made primarily of ...
